Definitions
- FIGs. 4A to 4E schematically illustrate apparatus for corrugating the nonwoven webs prior to necking.
- neckable material means any material which can be necked.
- nonwoven web means a web that has a structure of individual fibers of threads which are interlaid, but not in an identifiable repeating manner. Nonwoven webs have been, in the past, formed by a variety of processes such as, for example, spunbond processes, meltblowing processes and bonded carded web processes.
- Fig. 2B illustrates the desired relationship between the reduced width B of the corrugated nonwoven web 17, and the necked width C of the necked nonwoven web 22.
- the stretching length of path L c at the center of the nonwoven web is identical to the stretching length of path L e at both lateral edges and the tension along the edges is aligned with the web travel (machine) direction, eliminating the biaxial stress field.
- the ratio of the distance between cords 90 at exit location 94 and entrance location 92 is proportional to the ratio of the corrugated width B to the initial width A of the nonwoven web. If the desired corrugated width B is 50% of the initial width A, then the distance between adjacent cords 90 at location 94 should be 50% of the distance between them at location 92, as shown in Figs. 4D and 4E.
- the cords 90 may be formed of any suitably strong elastomeric materials such as polyurethane, polyethylene, polytetrafluoroethylene or polypropylene.
